[Use of a sinusoidal current of optimal frequency to stimulate the healing of skin wounds].

Local subthreshold electrostimulation of skin wounds with sinusoidal currents at a frequency of 300 Hz which is optimal for rats (the threshold of muscle contraction is minimal) improves microcirculation, reduces inflammatory processes, stimulates proliferation and differentiation of fibroblasts and epithelium, maturation of the granulation tissue, thereby accelerating the healing of linear and large incised wounds. The increase or reduction in the optimal frequency and exposure time (for over 15 min) decrease the beneficial effect of electrostimulation.
